Guess it's a good thing none of us here on the 'ol F150 forum have diesels! There's not a darn thing wrong with the reliability and cooling capacity of e-fans! Do some searching around here and I think you'll discover the vast majority of e-fan problems are with Troyer controllers and not the fans themselves or other quality controllers.

Maybe it's just me (and I apologize to the rest of the guys if it is just me) but it seems like every thread you're in, you're just in there bagging on something and/or stirring the pot with controversy. Don't think I've ever really seen you post up any productive assistance.

 

Diesel applications have a much higher heat load, which is an example of e-fans not having the cooling capacity of mechanical fan/clutchs.

All components will have a failure rate. Whenever you have more components in a system (like an e-fan cooling system) the system reliability will be much worse than a mechanical fan/clutch cooling system.

 

It's not only you Galaxy. it's a pretty well known fact. On another note, I would like to see a f150 with a 18,000 lb GVWR, so, someone is once again talking out, well, you know where. Maybe there is a reason all f150s from 2010 and up are all factory e-fans.

 

YUP, it's called CAFE!!

 

OOPS, sorry, forgot I was talking to the know all, do all god, Bye, Takeda !!

 

If you google mechanical fan conversions, you will see articles like this:

Sorry, but that thread doesn't really support anything. That attached article wasn't really about the capability of e-fans to cool the engine. I will admit some good points were made in that article in regards to keeping tranny and engine compartments slightly cooler because the mechanical fan runs all the time, but I'd that's your concern, wire in a switch ad let those fans run all the time.

You have to pick your poison here; can't have your cake and eat it too...I'll take the guarantees increased HP, throttle response, and fuel economy over the minor items mentioned in your linked article, but I'm sure you'll argue the pro's I've identified here, so....

 

I think to help circumvent a LOT of the issues with the Troyer controllers, TONS of dielectric grease should be used on every connection in the whole setup. Especially on and around the controller. If just a single drop of water falls into their non-waterproof controller it will crap out. I have ensured that my setup is like this now.

I like to wash my truck, so playing it safe is the way to go.

 

Let me help you out a little, since you missed the point. People are converting OEM e-fan setups to mechanical fan/clutch setups for increased reliability, and cooling capacity.

And be careful running your e-fan continuously, they aren't designed to run continuously. The OP's controller failing, causing the e-fan to run continuously probably caused the burn.

 

Check out post #49, he said his MPG has dropped an average of .5MPG with
the mechanical fan/clutch, which is hardly worth the much higher temps with the e-fan.

 

You mean your opinion that there are "much higher temps"

Did the data logging for the electric fans, and at the same time engine compartment temps for open filter elements FIPK ( the CAI argument ).

The hot air argument is full of hot air.

The facts :

The "cooling capacity" part of your opinion.... It does not hold water. Electric fans are not sub par when it comes to cooling even a supercharged 5.4L Ford V8.

 

The discussion was if an e-fan has the cooling capacity of a mechanical fan/clutch, and it doesn't.

 

It will cool the motor without an issue.
- It will cool a supercharged motor without issue after several 1/4 mi passes.

why do you keep trying to make it seem like it will not work ?
- Additionaly, which one did you test on your truck ?

 

One more time: The cooling capacity of an e-fan, and mechanical fan was being compared!!!!!!!!!!


Running above 35MPH doesn't require a fan at all, so running 1/4 mi passes says nothing about the cooling capacity of an e-fan!

 

So what was this about ?

- You made the statement about higher temps ( albeit from a jeep forum ).

So you now have a random statement about how a mechanical fan has more "cooling capactiy" than an E-Fan
- BTW : Where do you get this opinion from ( specific to a Ford, don't use a Jeep or Honda Ridgline as the basis, and not a 18K GVWR Ford )

On the track itself, yes
The return and pit area is below 35 mph, so more time is spent below 35 MPH ( after running the motor hard ).
Have you ever seen a 1/4 mi race track and the flow of the vehicles ?
